Sprinqua
Sprinqua is a self-hosted smart irrigation controller designed for Orbit OS and Raspberry Pi based systems. It allows you to manage irrigation zones locally through a fast and clean web interface, with no cloud dependency or external accounts.
With Sprinqua, you can build multi-zone watering programs — a single start time with zones running back-to-back, each with its own duration and an optional soak pause between them — manually pulse any output on demand, and let Smart Watering automatically skip or adjust irrigation based on weather. Skip Protection and duration Adjustment are independent: skip when today's rain or frost forecast crosses your threshold, automatically pause all programs for a configurable number of days after significant rainfall (with a one-tap manual override), or proportionally scale duration using a fixed percentage, a monthly curve, the Zimmerman ET method, or a Reference ETo (FAO-56) baseline calculated automatically from 12 months of local weather data — all powered by Open-Meteo, no API key required.
Zones can be freely configured at any time — rename them, set their type, maximum duration and manual pulse length, enable or disable individual outputs — and an optional exclusive mode ensures only one zone runs at a time. A dedicated Winter Mode lets you pause the whole system for the off-season without touching your schedules. All activity, including skipped runs, is logged locally with a 24-hour timeline chart, and your full configuration can be exported and restored at any time.
The system integrates seamlessly with Home Assistant via MQTT auto-discovery, enabling full control of zones and system modes directly from your smart home setup — including a passive mode where Sprinqua defers entirely to HA-managed automations.
